The 2:3 Neptune-resonance orbit for 1999 RK215 keeps the object more
than 15 AU from Neptune over a 14 000-year period.
On MPEC 2004-R27, the Mauna Kea observations of 1999 RB215 should have
been attributed to the 3.6-m Canada-France-Hawaii Telescope + CCD, not to
the 2.2-m University of Hawaii reflector + CCD.
